the 5-free promise

 Safe, clean beauty is the Essentialist way.


In our book, toxic chemicals fall into the non-essential category. From the beginning we’ve endeavoured to make luxurious, longwearing nail polishes that are safe for you whether you have sensitive skin, are pregnant or simply trying to clean up your beauty act. Manufactured in France, Dielle polishes are free from five key toxins found in many mainstream nail polishes:


1| Toluene 

This is a powerful solvent used to dissolve paint, rubber, adhesives and more. Toulene fumes can be very irritating to the skin, eyes and respiratory tract and prolonged skin contact can cause peeling and/or cracking. 

2| Formaldehyde

Commonly used in cosmetics as a preservative, formaldehyde is also used in the production of fertilizer, wood laminates, paper, embalming fluids and other industrial supplies. Under conditions with high or prolonged exposure, the U.S. Food and Drug Administration has classified it as a carcinogen. Many clean beauty groups caution against using formaldehyde in cosmetics, yet it is still found in many mainstream nail hardeners and nail polishes as an active ingredient to coat and strengthen the surface of brittle nails.

3| Dibutyl phthalate (DBP)

Banned for use in cosmetics in the European since 2004, DBP is a plasticizer used in nail polishes to reduce cracking by making the dry product less brittle. Independent studies have found that certain levels of the chemical can cause reproductive harm and distress to the endocrine system. 

4| Camphor

Though camphor has several medicinal uses, it can cause skin irritation and dermatitis with repeated use. More importantly, at certain concentrations, it’s been show to irritate mucous membranes and cause respiratory depression. 

5| Pthalic acid

Pthalic acid is used as a solvent in perfumes to make the fragrances last longer and in nail polish to prevent chipping, it's also an ingredient used in insect repellents as a dye carrier. In addition to all this, Pthalic acid is confirmed endocrine disruptor.
